The group said it will “explore innovative funding and technical solutions” to deliver broadband to rural areas and claims 90 communities in the UK are “already benefiting from this approach”.

The BT chief said the UK would “go beyond government’s current 95 per cent target for fibre availability, thanks to 'success dividend' clauses in contracts covering rollout co-funded by BT, Whitehall and local councils”.

He added: “The clauses mean BT has to reinvest or return money if take-up exceeds certain levels in areas where public funds have been used.

“A sum of £130 million is already being released and is potentially available to get the UK towards having fibre available at 96 per cent of premises.

“A greater proportion of premises will have access to fibre broadband than can access mains gas.”

BT secured all £490 million of state subsidies in the £1.2 billion rural broadband procurement programme, Broadband UK (BDUK) spread across 44 local bodies across the UK.

The Scottish Government pledged a further £2.5 million support in 2014 to help bring broadband to remote areas in Scotland, taking the total investment in the Community Broadband Scotland (CBS) programme to £7.5 million and extending the scheme until “at least March 2018”.

The Scottish Government and its partners are already investing £410 million in the Digital Scotland Superfast Broadband programme, which aims to roll out fibre broadband to 85 per cent of Scottish premises by 2015.

The government has also pledged a further £250 million in funding support from next year to help fill gaps in the national broadband network.

BT said it is now aiming to provide a universal broadband speed of between five and 10 Megabits per second (Mbps) for every home and business in the UK, “subject to regulatory support”.

Patterson, speaking at BT’s Delivering Britain’s Digital Future conference in London, pledged to tackle slow speeds in hard-to-reach parts of the country, begin rolling out ultrafast broadband from next year and improve customer service at its Openreach business.

He also announced plans to supply fibre broadband for all new housing developments, either through BT’s own efforts or in co-operation with developers.

He said: “For the past five years, the UK has been the largest digital economy in the G20, by percentage of GDP.

“We think the UK has an even brighter future ahead if we make the right decisions today.

“We want to forge an ultrafast future for Britain and stand ready to help government deliver the broadband speeds necessary for every property to enjoy modern day internet services, such as high definition TV streaming and cloud computing.

“To achieve this, we need a collaborative effort across industry and government.”

Patterson said new technologies developed at BT’s Adastral Park research laboratories “should help boost slow speeds for many hard-to-reach premises”.

New technologies being developed include “wireless to the cabinet” and “long reach VDSL (Very-high-bit-rate digital subscriber line) will help to bring higher speed broadband to hard-to-reach communities.

Patterson also pledged BT would introduce a satellite broadband service for some of the UK’s more remote premises by the end of the year.

BT Scotland director, Brendan Dick, said the proposals would have a “major impact on the future success and prosperity of Scotland”.

“BT is already leading the way with more than 1.8 million households and businesses in Scotland having access to high-speed fibre broadband - and that number is growing by around 7,000 a week,” he said.

“Now we are preparing to push ahead with the ultrafast broadband revolution and ensure that even people in the most challenging locations can get broadband capable of delivering sophisticated services, such as high definition video.

“In an increasingly competitive world, this further major investment will be another vital boost for our region.”

A report from the Public Accounts Committee (PAC) published in April 2013 found the the Department for Culture, Media and Sport had effectively given BT a monopoly in the £1.2 billion taxpayer-funded rural broadband programme.

BT picked up all 44 regional contracts awarded under the scheme, with PAC chair Margaret Hodge accusing the government of failing to deliver “meaningful competition” in the procurement of the programme.
